I heard that apart from the 4 claw option type, some joints were improved in the latter release, which were then applied to future productions of the MG mass production Z'Gok as well. This is akin to how the the improved waist introduced in Mk-II Ver.2 Titans color were applied onto the AEUG Version later.

How is the articulation of this model? Is it better or worse than the HCM Pro version?
